With 3.1.0-0.rc9.git0.0.fc16  I can no longer use wifi on this Acer 522. It tries to connnect to the network but it never establishes any connection. Using 3.1.0-0.rc8.git0.1.fc16 everything works fine.

Version-Release number of selected component (if applicable):
3.1.0-0.rc9.git0.0.fc16  

How reproducible:
Always

There are only two ath9k changes between rc8 and rc9 (I don't think we have something fedora specific).

    ath9k: Fix a dma warning/memory leak

which could cause this breakage. First one looks more suspicious.

Andreas, are you able to rebuild -rc9 kernel with patches reverted and see if that helps. Also could you attach dmesg output.

Comment 4 Andreas Tunek 2011-10-12 17:39:22 UTC 
Seems to work now. Perhaps it was some network-manager problem?
